TIM SINAK

Strength Coach

MS, CSCS, EP, USAW-L1

Tim received his BS in Nutrition and Exercise Science and MS in Exercise Physiology from the University of Missouri–Columbia. He is also a full-time instructor of Kinesiology at Colorado Mesa University, bringing a strong academic and evidence-based perspective to the Ridgeline coaching staff.

At heart, though, Tim simply loves the strength game. He has a particular passion for Olympic weightlifting and brings an uncommon level of technical precision and attention to detail to both his own lifting and his coaching. He continues to compete as a Masters weightlifter and has lifted at events including Masters Nationals, the Arnold, and the American Open.

Tim is the head coach and co-founder of Black Tree Barbell Club, a USA Weightlifting-registered club that calls Ridgeline home. Through Black Tree, he works primarily with high school athletes, along with a rotating cast of adult and Masters lifters.

Tim is recognized by the NSCA as a Certified Strength and Conditioning Specialist (CSCS), the ACSM as a Certified Exercise Physiologist (EP), and USA Weightlifting as a Level 1 Coach (USAW-L1).

When he's not teaching, coaching, or lifting, Tim enjoys getting outside and exploring the trails with his growing family.

Alexa Endsley

Strength Coach/Manager

Alexa is a graduate of Colorado Mesa University with a degree in Kinesiology and a minor in Psychology. A lifelong athlete, she competed in both gymnastics and tennis before moving into coaching, first as a gymnastics coach and later through strength and conditioning, and personal training.

While strength and athleticism remain central to her own training, Alexa has developed a broad curiosity about how people move and what keeps them capable over the long term. Her interests increasingly include trail running , mobility, and building the durability and resilience that allow people to keep doing the things they love outside the gym.

Alexa also works extensively with private training clients, ranging from kids to people in their 60s and 70s. That experience has helped shape a coaching perspective that looks beyond performance alone.

When she isn't coaching or training, Alexa is usually skiing, biking, camping, trail running, or finding another excuse to be outside—often accompanied by her dog, Boon, Ridgeline's unofficial assistant coach.

Katie Wickes

Strength Coach

Katie is originally from Littleton, Colorado, and earned her degree in Exercise Science from Colorado Mesa University. She is currently pursuing her Doctor of Physical Therapy degree at CMU, with an interest in eventually working in orthopedic or sports physical therapy.

Katie brings a thoughtful and genuinely curious approach to training. She is interested in the intersection of strength, movement, rehabilitation, and athletic performance, without being tied to any single training philosophy. Her own growth as an athlete has reflected that same openness. She has developed into a strong and confident lifter while continuing to run, hike, and spend time in the mountains.

Katie recently completed the 24-mile Telluride Mountain Run while in the middle of a strength-focused phase of her own training! She has also been involved with the CMU women's running community.

As a coach, Katie is caring, attentive, and eager to understand the “why” behind what she does. She brings her developing clinical perspective into the gym while remaining open-minded and willing to learn from both her education and her own experience under the bar.

Outside of Ridgeline and physical therapy school, you'll usually find Katie running, hiking, spending time with friends, or tracking down a good cup of coffee.

Jennifer Langford

Strength Coach

Jennifer is a graduate of the University of North Carolina at Charlotte with a degree in Communication Studies and is a licensed Physical Therapist Assistant. More recently, she has focused her career on youth athletic development and performance training.

Jennifer loves bridging the gap between physical therapy and strength and conditioning, with an emphasis on quality movement, developing strength and athleticism, and building confidence and lifelong habits around training.

A lifelong athlete, Jennifer grew up as a competitive swimmer and dancer before competing on the dance team at UNC Charlotte and later cheering professionally for the Carolina Panthers. Her diverse athletic and clinical background shapes her approach to helping people of all ages move well, get stronger, and feel more confident in the gym.

Outside the gym, Jennifer enjoys hiking, exploring new coffee shops, and spending time with her husband and their Dalmatian.

Liberdy Welsh

Strength Coach

Liberdy is a lifelong movement enthusiast with more than a decade of experience as a personal trainer and fitness instructor. An avid mountain biker, snowboarder, and all-around outdoor athlete, she brings an adventurous and playful approach to training that fits naturally with Ridgeline.

Since moving to Grand Junction in 2020, Liberdy has immersed herself in the local mountain biking community and earned her PMBIA Level 1 certification. She also coaches women mountain bikers, helping riders develop technical skills, confidence, and a greater sense of ease on the trail.

Liberdy’s own approach to movement extends well beyond conventional gym training. She loves to sprint, crawl, climb, tumble, lift, and explore different ways of moving and brings that same curiosity to her coaching. She believes strength and fitness should expand what you're capable of doing, whether that's navigating technical terrain, learning a new skill, or simply moving through life with more confidence.

As a wife and mom of two, Liberdy understands the value of training that supports a full, active life. Her coaching style is patient, encouraging, and grounded in meeting people where they are while still challenging them to discover what they're capable of.
